Sub Machine Guns
Sub Machine Guns in Call of Duty 4 are, in my opinion, the best weapon that you can choose. The major advantage to a SMG is that it is mobile, you can easily move around and make it harder for your enemy to hit you. Furthermore, the majority of SMG's have a high damage rate and a moderate accuracy, which is very beneficial in close quarters combat. However, the major disadvantage to SMG's (With the exception to the P90) is that they can not carry much ammunition; This can be disadvantageous in long range combat maps. In my opinion, the MP5 is the best SMG because it has a relatively high power, accuracy and ammunition count. I find it most effective without any attachments.
